| Popis: | As an important technique for developing high-precision gyroscopes, atom interferometry with continuous atomic beams has exhibited advantages of high short-term sensitivity and dynamic response relative to that with periodically launched atom clouds. This article reanalyzes the characteristics of an atomic beam interferometric gyroscope from perspectives including the continuous operation mode and the modified sensitivity dependence on laser and atomic sources. Specific requirements on certain experimental parameters are explored including the Raman beam diameter, detection beam diameter, atomic flux, laser power, laser phase noise, atomic longitudinal and transverse velocity distributions. The parameter determining strategy is discussed to achieve target sensitivity with controlled conditions such as system volume and operating bandwidth. The results would provide strong support on analytical method and data reference for further improvement of atomic beam interferometric gyroscopes. |
